DETACHABLE WHEEL-RIM.

Specification oi iietters Patent.

Application filed April 30 1910. Serial No. 558,653,

present the following, among other, salient and important advantages namely: 1. A detachable rim which shall be susceptible of easy and quick detachment from and attachmentto a wheel, with the minimum loss of time and delay and the consumption of a minimum amount of exertion; .2. A detachable rim which, by reason of its sim licity, maybe detached from and attache to. a wheel by the merest novice or tyro, dispensing with skilled labor; 3. A detachable rim which, when positioned upon the wheel, will not be pulled out of true by .the strain incident to the traveling automobile; and 4;. A detachable rim which may be manufactured and sold at a moderate cost.

With these expressly stated, fundamental objects in view, and also other objects of specific improvement appearing as the specification proceeds, my invention-comprises the novel construction, combination and arrangement of parts, as hereinafter fully described in the specification, summed up in the claims, and illustrated in the drawing.

In the drawing, which shows one embodimentof my invention capable of carrying out the underlying principles thereof, and in which like letters of reference indicate corresponding par'ts throughout the several views: Figure 1 is a side elevation, partly broken away, of a wheel (the spokes being omitted), showing my improvements appliedthereto; Fig. 2 is a transverse section through the wheel; Fig. 3 is a fragmentary detail view, looking down upon the inner or under face of the detachable outer rim; and

Fig. 4 is a fragmentary detail view, looking down upon the upper face ,of-the inner rim carried by the felly.

Referring, 'now, in detail to the drawing;

side a and,gat the other end. are provided with V-shaped noses at, the two walls of said V-shaped noses being, preferably beveled, as shown most clearly in F 4 of the drawing. I prefer to utilize six of these blocks at, equidistantly spaced apart, although a greater or a less number may be employed, as desired.

B designates a detachable, outer rim, carrying a tire CL This detachable rim B carries, in its inner or under surface, blocks 5, which are, at one end thereof, provided'with a V-shaped incutor notch, as at'b, the walls of said incut being preferably beveled. The

blocks 1) on the rim B are so arranged relative to the blocks a on the rim a that they may be brought intoengagement (in a manner and-by the means hereinafter appearing) with the blocks a the V-sha ed; ends or noses a of the blocks a exten ip g into the V-shaped incuts or notches bffwith a wedging and locking action.

a designates a wedge-key, which, as shown, is provided with one straight side adapted to engage'the straight end a of the block a, and with one inclined side a adapted to engage the similarly inclined side I)? ofabutments 6 carried by the inner or under surface of the -outer rim B, and positioned near one of the blocks 6. The wedgekey is also provided with a lateral, downturnedflange or head a. Preferably, two of these wedge-keys a are provided and, advantageously, they are disposed at diametrically opposite points on the wheel, as shown clearly in Fig. 1. As two wedge-keys are preferably used, two abutments b (as shown in Fig. 1) must, of course, be employed, one to cotiperate with each key.

Though different methods and means for locking the wedge-keys a in position will readily suggestthemselves, I have,-in this instance, shown', as an example of one means,

Patented Oct. 11, 1910.

a bolt a extending transversely through the felly A, and which may be secured in position in any manner, as by being riveted at one end to the inner rim a, as shown at a. The other end of the bolt a is threaded, as at a, and projects through the head or flange (L -of the wedge-key a and carries a nut a and 4). I

The operation of, the device is as fol ows: In placing a detachable rim B on a wheel, the said-rim is slipped onto phe wheel in such position thatcthn blocks a on the in- (all as clearly shown in Figs l, 2

erase-1 ner rim a lie between the blocks 6 and the abutment-s 5 then the wedgekeys a are thrust in between the abutments 5 and the blocks a and the nuts a .tightened,the inclined side a of the Wedge-key a wedging against the inclined side 6 of the abutment b and the straight side a bearing against the straight end a of the block a carried by the inner rim a, whereby the outer rim B is moved or revolved slightly to cause the V-sha ed ends or noses a of the blocks a to we ge firmly in the !shaped notches of the blocks W hen it is desired to remove the detachable outer rim 3, to replace it by another, all that has to be done is to remove the nuts a and keys a when the outer rim may be turned or revolved slightly to free the blocks a from looking engagement With'the blocks 6, and the outer rim then slid oli from the Wheel. It will be nderstood, oi course, that the nuts as, whether th" automobilewheel be-on the right or the left-hand side of the automobile, are on the outer side of the Wheel, so that they may be easily reached.

then take out the Wedgein order that the detachable rim B may be i each having a \l-shapcd nose, a detachable placed on a Wheel which is on either the right or left hand the under or inner face of the outer rim B carries, intermediate of the six blocks 6 and equidistantly synced apart, additional blocks (preferably six in number) and two additional abutments 0" (only ouebeing shown in the drawing), these additional blocks and abutments being reversely dis- Eosed with reference to the position of the locks Z) and abutments b (as clearly shown in Fig. Thus, the outer detachable rim B may be used either right left hand, as may be required, in the particular emerncy or ezrigsncy.

I am aware that many modifications in detail may be resorted to, without affecting the spirit of the invention, and all such modifications as come within the scope of the apnended claims, are Within the purview of side of the automobile,

Letters-Patent is 1. In a wheel having an inner rim, a detachable outer rim, wedge-blocks carried on the outer surface of said inner rim, and each having a V shaped nose, complementary blocks carried by the inner surface of said outer rim, and each having, at one end, a V- shaped notch engageable by one of said V- shaped noses,-and means for locking the detachable rim in place.

2. In a wheel having an inner rim, a detachable outer rim, wedge-blocks carried on the outer surface of said inner rim, and each having a V-shaped, beveled nose, complementary blocks carried by the inner surface of said outer rim, and each having, at one end, a V-shaped notch engageable by one of said l-shaped noses, the Walls of eacn notch being beveled, and means-for locking the detachable rim in place.

3. In a wheel, an inner rim, Wedge-blocks carried on the outer surface thereof and outer rim, complementary blocks carried by the inner surface thereof, and each having, at one end, a V-shaped notch cngageable by one of said ii-shaped noses, and means for locking said blocks in cooperative engagement, with the nose of each'o'f said wedge blocks forced into the V-shaped notch of the corresponding notched bloc-k, said means comprising wedge-keys carried by the wheel, and means for locking the wedge-keys and, thus, the detachable rim against movement. In testimony whereof-I have l" ereunto set my hand in presence of two subscribing witnesses.
